make sure you have ADB working!!http://forum.xda-developers.com/showthread.php?t=865685
I found "Method B" to be the quickest and easiest way to use ADB- just download from Step 2, move the entire extracted folder to C:\ and rename it ADB for easy access within the command prompt.

takes a bit of work and time.. but I am now back to factory and can send this G2 back to TMo (my keyboard went wonky and they sent me a replacement). I think I'm upgrading to the HTC One S very soon.
I am tempted by the Galaxy Note.. but.. I don't trust Samsung.. love me some HTC.

now to root and load CM onto the new one! maybe.. there really isn't a point if I'm just passing along to Rylie when I upgrade.

edit: nope.. need root and CM. stock pisses me off. and hot damn.. I never did a write-up on how to do root. project for another day...
